NVIDIA GeForce GTX 780 Reviewed – 25% Faster Than GTX 680

If you had been following us then you would know that the GeForce GTX 780 is based on a slightly cut down version of the GK110 core which was featured on the GeForce GTX Titan. The GTX 780 would be the flagship product of the 700 series and would be based on a cut down version of the GK110 core codenamed “GK110-300-A2″. This core would have 2304 cores and a 3 GB GDDR5 memory which would operate along a 384-bit memory interface. The core is maintained at 863 MHz with Turbo boost of 900 MHz while the memory operates at the reference 1502 MHz or 6 GHz effective clock speed. The GPU would be powered by an 8+6 Pin connectors which represent a 250W TDP while display connectors include Dual Link DVI, HDMI and a single display port. Following is the specification sheet for the GPUs tested:
